Abstract

I én fremstilling representerer denne anordningen et gripesystem for en tang, for å sammenføye rørforbindelser og skru rørforbindelser fra hverandre. Gripesystemet er koblet til tangens dreiebord. Gripesystemet inkluderer en aktiv kjeve og to passive kjever som er montert på dreiebordet. De to passive kjevene skal helst være montert i en avstand på under 120 grader fra hverandre og er forbundet til dreiebordet ved et hengsel. Gripesystemet er konstruert og tilpasset for å la hver passive kjeve reagere med samme kraft som gripekraften som påføres av den aktive kjeven. I en annen fremstilling innlemmer konstruksjonen en mekanisk rotasjonslås for å låse eller frigjøre tangens dreiebord.In one embodiment, this device represents a gripping system for pliers, for joining pipe connections and screwing pipe connections from each other. The grip system is connected to the pliers turntable. The grip system includes an active jaw and two passive jaws mounted on the turntable. The two passive jaws should preferably be mounted at a distance of less than 120 degrees from each other and connected to the turntable by a hinge. The gripping system is designed and adapted to allow each passive jaw to react with the same force as the gripping force applied by the active jaw. In another embodiment, the structure incorporates a mechanical rotary lock to lock or release the pivot table.
